Tece Sta uses Marketo for marketing email and Amazon SES for transactional/notifications. We've also observed sends via 3 other providers: SendGrid, Wix, HubSpot. Their email authentication setup is good (score 70/100). Missing: DMARC enforcement. We've recorded 2 ESP changes since first observing this brand.
Amazon SESAuthentication signals observed in this brand's emails. SPF, DKIM and DMARC are the standard sender-authentication stack — see the DMARC policy below for whether spoofing is actually blocked or just monitored. One-click unsubscribe meets Google & Yahoo's bulk-sender requirements.
SPF / DKIM / DMARC above reflect the last 6 emails we've observed. DMARC policy is read live from DNS.
DKIM alignment: observed emails sign with a third-party DKIM key (tece-sta-co-jp.20251104.gappssmtp.com) — DKIM passes there but doesn't align with tece-sta.co.jp, so DMARC has to rely on SPF alignment.
TLS: modern — 100% TLS 1.3 (across 8 sends).
Delivery (last 7 days): 33% under 10 seconds, 0% over 1 minute (across 6 sends).
Brands often use multiple ESPs (e.g. one for marketing, another for transactional/notifications).
SendGrid 3 Wix 2 HubSpot 1ESPs we've seen sending email for this brand. Green = confirmed by SPF, sender IP rDNS, or known infra pairing (label shows the source). Grey = observed but not yet confirmed by SPF or PTR.
No SPF record published on the apex tece-sta.co.jp. Emails from this brand still pass SPF — most ESPs handle SPF on a sending subdomain (Return-Path) rather than the apex. Adding an apex SPF (even v=spf1 -all) would block direct spoofing of unused From: addresses.

Folder distribution across all emails from this brand observed in Gmail inboxes. High inbox % = good deliverability; spam appearances are the headline signal.
| Folder | Count | Share |

Which ESP's emails are landing where. Sorted by spam % so problem senders surface first. Brands using one ESP for marketing and another for transactional often see very different placement profiles per ESP. Per-ESP folder data only started being captured recently — counts here may be smaller than the total above until backfill catches up.

Daily observations per ESP. Brands often run multiple ESPs concurrently — marketing on one, transactional on another — so this chart shows usage rather than switches.
